[英]Conflict between shinyBS::bsCollapse and shiny::conditionalPanel
我在 shinyBS::bsCollapsePanel 內使用shiny::conditionalPanel
shinyBS::bsCollapsePanel
。 我的應用程序中有邏輯取決於哪個shinyBS 面板處於活動狀態(即展開)。 這工作正常,直到我激活條件面板。 如果我顯示 Shiny 條件面板,那么即使面板處於非活動狀態(即關閉),shinyBS 折疊面板也會卡在活動狀態。
如何修改我的代碼,以便可折疊面板僅在展開時才注冊為活動面板?
在此示例中,有一個文本 output 指示活動面板。 除非顯示條件面板,否則面板之間的切換可以正常工作。
編輯:看來這個錯誤可能已經記錄在案( https://github.com/ebailey78/shinyBS/issues/38 )並且有一個可能的解決方案( https://github.com/ebailey78/shinyBS/pull/68/提交)。
library(shiny)
library(shinyBS)
# Define UI logic
ui <- fluidPage(
htmlOutput("activePanel"),
shinyBS::bsCollapse(
id = "bsPanels",
shinyBS::bsCollapsePanel(
"Panel A",
value = "panelA",
checkboxInput("showPanelA",
"Show panel",
value = FALSE),
conditionalPanel(
condition = "input.showPanelA",
helpText("Panel A conditional content")
),
helpText("Panel A main content")
),
shinyBS::bsCollapsePanel(
"Panel B",
value = "panelB",
checkboxInput("showPanelB",
"Show panel",
value = FALSE),
conditionalPanel(
condition = "input.showPanelB",
helpText("Panel B conditional content")
),
helpText("Panel B main content")
)
)
)
# Define server logic
server <- function(input, output) {
output$activePanel <- renderText({
paste("<b>Active Panel:</b>", paste(input$bsPanels, collapse = ", "))
})
}
# Run the application
shinyApp(ui = ui, server = server)
在shinyBS 項目頁面( https://github.com/ebailey78/shinyBS/issues/38 )上有一些關於這個問題的討論。 但是,我對所提出的解決方案的成功有限。
我發現的最佳解決方案是使用shinyjs::showElement
和shinyjs::hideElement
。
library(shiny)
library(shinyBS)
library(shinyjs)
# Define UI logic
ui <- fluidPage(
useShinyjs(),
htmlOutput("activePanel"),
shinyBS::bsCollapse(
id = "bsPanels",
shinyBS::bsCollapsePanel(
"Panel A",
value = "panelA",
checkboxInput("showPanelA",
"Show panel",
value = FALSE),
uiOutput("condPanelA"),
helpText("Panel A main content")
),
shinyBS::bsCollapsePanel(
"Panel B",
value = "panelB",
checkboxInput("showPanelB",
"Show panel",
value = FALSE),
uiOutput("condPanelB"),
helpText("Panel B main content")
)
)
)
# Define server logic
server <- function(input, output) {
output$activePanel <- renderText({
paste("<b>Active Panel:</b>", paste(input$bsPanels, collapse = ", "))
})
# Logic for conditional panels
output$condPanelA <- renderUI({
helpText("Panel A conditional content")
})
observe({
if(input$showPanelA) {
show("condPanelA")
} else {
hide("condPanelA")
}
})
output$condPanelB <- renderUI({
helpText("Panel B conditional content")
})
observe({
if(input$showPanelB) {
show("condPanelB")
} else {
hide("condPanelB")
}
})
}
# Run the application
shinyApp(ui = ui, server = server)
